Diffutils 3.11 fail exactly as 3.12 do.
Diffutils 3.10 did not compile here since May 2023, see for example:
https://trac.macports.org/ticket/67488, https://trac.macports.org/ticket/67248,
https://trac.macports.org/ticket/68964.
They were never installed here (from time to time I am recording what is
installed). This little patch, as taken from the resolutions of tickets
mentioned above, makes diffutils 3.10 compile:

Well, what can I write, or cite:

(Even the line numbers are the same as on my High Sierra Mac.) I tried also a
few more pairs to diff from some regular routine, and all was successful. So
the bug was introduced quite recently between versions 3.10 and 3.11.
If bisecting with git does not bring a result, I'd try a parallel GDB session
in two Emacsen with both. (A Mac allows to use an X client, the NeXTStep
successor, and the "Carbon" unofficial variant.) This might show differences in
behaviour.
